php - mysql查询失败

Question

mysql查询有点问题

我有两个表A和B

table A {id, name, gender}
table B{id, name, salary}

我想查询name, gender, salary，但我的查询似乎只有name和gender

查询是:

select * from tableA inner join tableB on tableB.id=tableA.id ;

Answer 1

SELECT a.name, a.gender, b.salary
FROM tableA AS a
LEFT JOIN tableb AS b ON(a.id = b.id)
WHERE 1;
